Comprehensive Attic and Crawl Space Sealing in Guilford to Prevent Drafts and Moisture

Are you worried about moisture creeping into your crawl space and causing damage? Our team in Guilford, Connecticut, provides complete attic and crawl space sealing services to help protect your home. Using advanced tools like blower door tests, we find exactly where air is leaking and seal those gaps using high-quality spray foam insulant, caulk, or sealant. These small fixes make a big difference. By sealing off these hidden openings, we reduce drafts, prevent cold air from slipping in, and keep your heating or cooling from escaping. In crawl spaces, we go even further with full encapsulation. That means cleaning out the area, sealing every crack, installing a vapor barrier to block moisture, and adding a dehumidifier when needed. This keeps your home dry, your foundation protected, and your indoor air healthier.
